Tropaeolum polyphyllum

A hardy tuberous perennial Nasturtium. Pale blue-grey leaves meticulously arranged all along long trailing stems make it worth growing for foliage alone. Pretty lemon yellow flowers erupt from the tip of each stem in June and July. By August it has become dormant and you will see no more of it until next April.

Sow fresh and it may germinate in a month. Otherwise will need prolonged cold period to break dormancy
